Astrid is a Sophomore in high-school, living in the historic city of Berk. Her grades are failing and she has two options: find a tutor and possibly destroy her reputation as the most popular girl in school, or be assigned one and never play a school sport again. Little does Astrid know, that an option three is going to present itself soon. One day on her way home from school a handsome but gimpy stranger runs out of an alley and knocks her over. This stranger is quickly followed by three men in black suits who are asking if anyone has seen the boy. A week later Astrid manages to locate the boy and she confronts him about his identity. Turns out this gimpy boy's name is Hiccup, and he is under the constant protection of the FBI. See, Hiccup is a technological genius and the worlds greatest hacker, he is being hunted by Gang Lords so that they may posses his genius and use it for evil purposes. That's not even mentioning the dragon he is protecting after it was thawed out of an iceberg. Maybe this Genius is just what Astrid needs, and maybe he needs her just as much. Who else could successfully keep him out of trouble? Certainly not the FBI!
